Development of Crossover and Encryption Based Text Steganography (CEBTS) Technique

Abstract

This paper presents new text steganography approach named as Crossover Encryption Based Text Steganography (CEBTS) approach. This approach is a combination of random character sequence and feature coding method. In this approach in order to hide the secrete message, we first encrypt the message and then mix it in the cover text. Cover text is generated by random character sequence. In this approach the key is generated from the very first three character of the cover text by using crossover technique between these three characters. This generated key will be used to encrypt the plain text and this key will also used to decide that how the encrypted message will hide with cover text. For this approach we have developed two algrithms, one is for key generation using crossover technique and then encrypt the message using this key and hide the encrypted message into cover text using this key and second is used to retrieve the secrete message. We are also presenting comparison of our proposed approach with some of the previous popular text steganographic approaches with execution time and also the length of cover text which will be required to encipher using n bit cover text. At the last in our conclusion section we are showing that how our approaches are performing best in the existing approaches.
